The signature ridge road of the Tramuntana is also the corridor riders ask about most. Unlit tunnels, no shoulder, blind hairpins and a steady summer mix of motorcoaches and rental cars. Avoid descending in fading light; use a rear flasher in every tunnel even at midday. No per-road casualty figures are published for it.

MA-2141 — MA-2141 — Sa Calobra access road Risk 5 of 5
26 km out-and-back to the sea with a single narrow lane shared between climbing cyclists, descending cars and the daily tourist-boat coaches up from Port de Sóller. The dead-end character means traffic peaks predictably between 10:00–14:00. Start the climb before 09:00 and exit before noon, or wait until after 17:00.

About safety on Sa Calobra
Safety on Sa Calobra comes down to three things. First, the road is a dead end with 12% maximum gradient, so fast riders on the descent meet tired riders climbing back, and the hairpins and the Nus de sa Corbata punish any line that wanders. Second, coaches arrive from about 10:30 and are wide for a narrow road, so ride early or accept sharing. Third, the climb is fully exposed: heat and dehydration are the real risk in summer. Our map shows a defibrillator about 0.5 km from the foot of the climb in the cove. Check the Ma-2141 road-risk page and the MA-10 tunnel notes before you set out.
